Overview of areal changes of the ice shelves on the Antarctic Peninsula over the past 50 years [PDF]
The Cryosphere, 2010 In recent decades, seven out of twelve ice shelves around the Antarctic Peninsula (AP) have either retreated significantly or have been almost entirely lost. At least some of these retreats have been shown to be unusual within the context of the Holocene

, 2020 The OASIIS Working Group is a community of scientific researchers working together to improve observations and our knowledge of the oceans beneath Antarctic sea ice and ice shelves. This fact sheet provides an overview of the SOOS - POGO Working Group on

The Role of Ice Shelves in Antarctica, Ice Shelf Variation Across Antarctica and the Mechanisms Behind Ice Retreat [PDF]
, 2016 Ice shelves are an important component of Antarctica, they restrict the flow of glaciers at the edge of the Antarctic Ice Sheet (AIS) therefore limiting any loss of ice from the ice sheet.

Advances in Climate Change ResearchWidespread supraglacial lakes (SGLs) across the Antarctic surface can accelerate land ice flow and be linked to ice shelf disintegration, further affecting sea-level rise projections. However, previous studies usually focused on SGLs at regional scale or

Deformation of Floating Ice Shelves [PDF]
Journal of Glaciology, 1957 AbstractThe problem of the creep deformation of floating ice shelves is considered. The problem is solved using Glen’s creep law for ice and Nye’s relation of steady-state creep (the analogue of the Lévy-Miles relation in plasticity theory). Good agreement is obtained between an observed creep rate at Maudheim in the Antarctic and that predicted from ...

Journal of GlaciologyThe conditions under which ice fractures and calves icebergs from Antarctic ice shelves are poorly understood due largely to a lack of relevant observations. Though previous studies have estimated the stresses at which ice fractures in the laboratory and

Ocean warming threatens the viability of 60% of Antarctic ice shelves
International audienceThe disappearance of ice shelves, the floating margins of the Antarctic ice sheet that restrain the ice flow into the ocean, would strongly accelerate the Antarctic contribution to sea-level rise.

Mechanical analysis of pinning points in the Ross Ice Shelf, Antarctica
Annals of Glaciology, 2019 Ice shelves regulate the rate of ice-sheet discharge along much of the Antarctic coastline. Pinning points, sites of localised grounding within floating ice, can in turn, regulate the flow and thickness of an ice shelf.

Basal channels on ice shelves [PDF]
Journal of Geophysical Research: Earth Surface, 2013 Recent surveys of floating ice shelves associated with Pine Island Glacier (Antarctica) and Petermann Glacier (Greenland) indicate that there are channels incised upward into their bottoms that may serve as the conduits of meltwater outflow from the sub‐ice‐shelf cavity.

On the non-linear response of Antarctic ice shelf surface melt to warming [PDF]
The CryosphereSurface meltwater can saturate firn, form melt ponds, and trigger hydrofracturing of Antarctic ice shelves, ultimately accelerating grounded ice flow and contributing to sea level rise.
